I can’t see it very well but if a 4 is next to the x then the answer would be x = 16.

Answer: The fourth term is -102

----------------------------------------------

Explanation:

The term after the nth term is generated by this rule $a_{n+1} = -4(a_n) + 2$ which means that we first
Step 1) multiply the nth term ( $a_n$ ) by -4
Step 2) Add the result of step 1 to the value 2 to get the next term in the sequence

Let's follow those steps above to generate the first four terms

The first term is $a_1 = 2$ . In short, the first term is 2

The second term is...
$a_{n+1} = -4(a_n) + 2$
$a_{1+1} = -4(a_1) + 2$
$a_{2} = -4(2) + 2$
$a_{2} = -8 + 2$
$a_{2} = -6$
So the second term is -6

The third term is...
$a_{n+1} = -4(a_n) + 2$
$a_{2+1} = -4(a_2) + 2$
$a_{3} = -4(-6) + 2$
$a_{3} = 24 + 2$
$a_{3} = 26$
The third term is 26

Finally, the fourth term is...
$a_{n+1} = -4(a_n) + 2$
$a_{3+1} = -4(a_3) + 2$
$a_{4} = -4(26) + 2$
$a_{4} = -104 + 2$
$a_{4} = -102$
The fourth term is -102.

Can someone help me with this question

Tasya [4]

I’m pretty sure you add 78+55= 133
180-133=47
so 9x+2=47
subtract 2 from 47 and itself
so 9x=45
divide 9 and 45 by 9
so x=5

Try graphing using the x-intercept and y-intercept.

-15x - 5y = 45

Put in x = 0 to get -5y = 45, making y = -9. Point (0, -9) is on the line.

Put in y = 0 to get -15x = 45, making x = -3. Point (-3, 0) is on the line.

-2x + 6y = 6

Put in x = 0 to get 6y = 6, making y = 1. Point (0, 1) is on the line.

Put in y = 0 to get -2x = 6, making x = -3. Point (-3, 0) is on the line.

(We've actually stumbled on the solution since (-3, 0) is on both lines!)

Graph the two lines using the points found above.

The solution is x = -3, y = 0.
